中波载频即发射机输出网络的中心频率,高端是低端的3倍。调试时,可能导致输出网络的带宽在高端比在低端宽得多,而我们希望基本不变。本文介绍了10KW-DX中波发射机输出网络的电路结构和计算方法,提出了克服带宽随载频变化的解决方法,对提高广播音质有重要意义。 Medium wave carrier frequency is the transmitter output network center frequency, high-end is 3 times the low end. Debugging may result in the output network bandwidth being much higher at the high end than at the low end, and we hope it will remain essentially the same. This paper introduces the circuit structure and calculation method of 10KW-DX medium-wave transmitter output network, and puts forward a solution to overcome the change of bandwidth with the carrier frequency, which is of great significance to improve the sound quality of the broadcast.
